The intention of this post is to tell you of the various types of eyeBolts obtainable; taking a look at the pro's and conís and uses of each, so therefore allowing you to decide which type will be the most suitable for your exact requirements.

There are countless eyebolts in the market place these days, every one with various properties and capacities, so there is certainly basically something for each situation. Eyebolts generally screw into a suitable location to produce a fixing point from where to connect your chain slings etc. ready for lifting. The standard form of eyebolt should only be utilised to lift from a vertical position, however the swivel type of eyebolt enables lifting from virtually any angle and are consequently more versatile and becoming enormously popular. An additional variant of eyebolts are the bownut and eyenut; these are screwed onto a permanent and threaded bolt.

Choosing the correct type of lifting/suspension point is a task to be thought carefully about, make sure you go for an eyebolt to suit the type of sling you may be utilizing, or much better still, one that will go well with most styles of slings, whether it is a chain sling, web sling or rope sling. If you do not choose a suitable variety you might end up adding extra fixings to make the sling fit, this is not good practise and could be unstable. The safe working load capacity is also an important issue to think about as is the sort required, will you just need an eyebolt which is for in-line/straight lifts only such as the standard eyebolt, or else do you need one which may be loaded at all angles, for instance the swivel eyebolt. Deciding on the best one to match your needs will save time, money and also safety issues which may take place.

The size and also form as well as the heaviness of the load that is intended to be lifted should be looked at along with the quantity of anchor/lashing points that will be needed and the angle at which the sling will need to be utilised. Different angles affect the lifting capacities of slings. Sufficient anchor points must be available to facilitate a stable lift, with the total safe working load capacity never exceeded. The position of the eyebolts will need cautious consideration as well and also make sure the location where they are attached is able to generate a secure thread hole for the bolt and can also take the weight of the load. They ought to also be placed to work well with the preferred slinging system.

The bulk of eyebolts are made from high tensile, drop forged steel, which makes them particularly strong, the standard varieties can be finished in its self colour, electro-galvanised or hot dipped galvanised; you will find some eyebolts obtainable which are made from stainless steel to provide appropriate anchor point s for areas with high chlorine concentrations and sea water. At the top end of the vast array of eyebolts are the ones that have a exclusive finish in which the original colour clearly changes whenever the temperature increases, permitting the working load limit to be reduced at certain temperatures, which can be of vital importance.

Shock loading, twisting of the load as well as hard vibrations can all cause the eyebolt to become loose, sometimes to the extent where it could turn out of its cavity totally; for this reason if eyebolts are going to be used where these conditions do or may well happen then it's suggested to apply special adhesive to the bolts on installing or maybe a crown nut with a key or counter nut, in order to prevent the eyebolt from becoming unsafe.

As with every type of equipment utilised for lifting loads you will find vital protocols in place to ensure safety, and thus ought to be followed at all times when using eyebolts of any kind, the fundamentals are as follows; Inspect prior to each use to ensure there is no damage, for example, cracks, distortions and gouges, they must be seated correctly and also the swivel type should revolve easily; capacity markings must be clear. In addition, whilst in use; single suspension points have got to be in the direct line of gravity; several points must be in the same lifting plane/angle, as well as evenly spaced around the centre of gravity. Eyebolts are considered to be small or loose lifting gear so therefore is required to be professionally checked over at six monthly intervals.

To conclude, it is apparent that eyebolts are presented for different situations, and supply a great anchoring/suspension point for lifting and also lashing purposes. Checked frequently, fitted and also utilised appropriately they should provide a strong and safe fixing point.
